Weapon and Armor
Proficiency:

Experts are proficient with all simple weapons, plus one martial weapon
of their choice. Experts are proficient with light armor and shields.

Surge:

Experts can do a lot with their skills. To help them, they have a
number of surges per day equal to their Expert level. These surges can
be spent on various abilities. Unless noted otherwise, spending surges
does not require an action.

Push (Ex):

Experts can push themselves to greater skills. As part of a skill
check, the expert can spend a surge to gain a competence bonus on that
check equal to their expert level. They may use this only on skills
where they have at least 1 rank.

Assist (Ex):

Starting at level 2, experts can help others as well as themselves. By
spending a surge, the expert can grant a competence bonus on a skill
check made by someone else equal to their expert level -1. You must be
within 10 feet of the creature making the skill check. They may use
this only on skills where they have at least 1 rank.

Study (Ex):

Starting at level 2, experts can study to pick up new material. By
studying for 1 hour, the expert may choose a skill. They gain 2
"phantom" ranks in the chosen skill (up to the maximum number of ranks
they can have in that skill). These "phantom" ranks remain until the
next time the expert uses this class feature.

Starting at level 7, the expert can spend a surge to use this class
feature more swiftly. If used in this way, it takes 1 minute of study.

Skill Trick (Ex):

At levels 3 every odd numbered level after that, the expert gets a
skill trick from the list of skill tricks.

The expert must have at least 3 ranks in the skill tied to the skill
tricks they choose.

Deeper Study
(Ex):

At levels 4, 10 and 16, the expert gets Skill Focus in the skill of
their choice as a bonus feat.

Steady (Ex):

Starting at level 6, experts can do things in a steady way. By spending
a surge, the expert can take 10 on a skill check even if they are
threatened or distracted. They may use this only on skills where they
have at least 3 ranks.

Re-commit (Ex):

Starting at level 8, the expert branches out into new fields. Their
skill points per level for the Expert class increases to 6 +
Intelligence score. This increase applies retroactively.

Starting at level 20, their skill points per level further increase to
7 + Intelligence score. This increase also applies retroactively.

Retry (Ex):

Starting at level 10, the expert can retry things quickly. By spending
a surge, the expert can reroll a skill check they just made. They may
choose to use this ability after finding out if the first check passed.
A single skill check may only be rerolled once. They may use this only
on skills where they have at least 7 ranks.

Re-study (Ex):

Starting at level 12, the expert can study up on topics they don't
know. By studying for 1 hour, the expert may choose a number of skills
equal to their Intelligence score. They gain a number of "phantom"
ranks in the chosen skill equal to half their expert level + 2 (up to
the maximum number of ranks they can have in that skill). These
"phantom" ranks remain until the next time the expert uses this class
feature.

Starting at level 17, the expert can spend a surge to use this class
feature more swiftly. If used in this way, it takes 1 minute of study.

Epic Skill Trick
(Ex):

Starting at level 14, the expert develops a trick of unrivaled power.
They get a skill trick of their choice; they must have at least 3 ranks
in the skill tied to the chosen trick. They may choose an Epic Skill
Trick, ignoring the requirement to be epic those tricks normally have.

Re-think (Ex):

Starting at level 16, the expert can change their focus. By studying
for 1 hour, 5 skill points the expert has spent (the expert chooses
which 5) are refunded and can be re-spent.

Perfect (Ex):

Starting at level 18, the expert can hone their craft to perfection. By
spending 2 surges, the expert can take 20 on a check where they would
have taken 10, but without taking 20 times as long or triggering
failure. They may use this only if they have at least 15 ranks in the
skill in question.
